Wave energy is seen as the largest untapped source of renewable energy on the planet: ENEA and RSE have calculated that if this could be fully harnessed, we could obtain 2 TeraWatts of energy, around 18 trillion kilowatt hours per year, almost equal to the entire world’s annual electricity demand. Moreover, wave energy is predictable, more regulated and constant than other renewable sources. Our ISWEC system does exactly that: it converts the energy of ocean waves into electrical energy, making this immediately available for off-shore plants or feeding it directly into the electricity grid to provide power to coastal communities. The full name of this system is the Inertial Sea Wave Energy Converter , and we developed it in collaboration with Wave for Energy S.r.l, a spin-off of the Politecnico di Torino. The system consists of a sealed floating hull containing a pair of gyroscopic systems , connected to two generators. The waves cause the unit to pitch; it is anchored to the ocean floor, but free to move and oscillate. This pitching movement is intercepted by the two gyroscopic systems which are connected to the generators, and these in turn transform this movement into electrical energy. A simple solution, with cutting-edge technology at its heart. Besides waves, there are many other ways the sea can provide clean energy.
To study and make the most of all the potential of seas and oceans, in collaboration with the Polytechnic of Turin, we have created MORE (Marine Offshore Renewable Energy Lab), a laboratory given over entirely to creating technologies to exploit not just waves, but also ocean currents, tides and the salinity gradient, as well as to improve wind and solar offshore.
Our commitment to the development of the renewable marine energies sector has been further reinforced by joining, as lead partner, Ocean Energy Europe (OEE), the largest European network for the development of ocean energies. This position allows us to collaborate to chart the strategic course of OEE with the aim of commercialising marine technological solutions.
